Chapter 1, Problem 1.18RQ
Explanation of Solution
Components of
The database system constitutes of the key parts mentioned below:
- DBMS (Database management system)
- Database
- Database application
- User
Database management system:
- Database management system is a set or collection of
programs also known as system software which enables users to create, process, and administer the database. - It acts as an intermediary between programs and data.
- Programs can get the access over data only through database management system which also maintains the required features of the data.
Database:
- Database is defined as the organized set of tables, views, and other elements...
